    It's been a few years since I've been in school for this, and I need a refresher on how clock and data works.

    I have a device that has clock/data (data0/data1) outputs and I need to understand (again) the basics behind this.

    Can someone post a (hopefully) simple rundown, or provide a link to a document that explains it?

    Sorry to ask such a basic question, but my brain only holds so much and this information wasn't used much over the last 10 years.

    Since the clock and data signals are outputs you just need to be concerned with the clock phasing. On one clock edge the data is meant to be read from the data line, while on the opposite clock edge the data will change on the data line. Be sure to know which is which.
